Celestia is a 3D astronomy program based on the Hipparcos Catalogue (HIP) and allows users to travel through an extensive universe, modeled after reality, at any speed, in any direction, and at any time in history. Celestia features and interacts using physical objects which range inside level by tiny spacecraft to overall galaxies inside a few size using OpenGL, by viewpoints which may not necessarily be achievable from your typical planetarium or perhaps various other ground-based show.
Contrary to many planetarium application, Celestia will not constrict that you the top of Soil. You can journey throughout the solar system, to any kind of above 100, 000 stars, and even further than this universe.
All motion with Celestia are seamless; this rapid glide element permits you to discover space across a big range of scales, through universe groups and down to spacecraft only a few meters across. Any 'point-and-goto' interface can make it an easy task to find the way over the world towards target you wish to pay a visit to.
Celestia is expandable. Celestia is actually expandable. Celestia comes with a huge collection of stars, galaxies, planets, moons, asteroids, comets, along with spacecraft. If that is too few, you are able to acquire a large number of simple put in add-ons with more physical objects.
